ucts in which one of the seams is arranged in line with and in closeproximity to a fold in the'fabric being acted on, the fold acting todetermine the relative arrangement of the complemental seams.

Referring to the drawings, Figures 1, 2,

3 and 4 are views in front elevation, side elevation, rear sideelevation. and in a plan, respectively of the present invention, andFig. 5, one variety of product ll(-.15ll1 Si1OWll for a betterunderstanding of the invention.

Referring to the figures, 1 .represents'the ordinarycloth-press-carrying-bar mounted in suitable bearings formed in the head2 of one form of commonly employed bracket- (not shown), the usualspring 3 and collar being employed to yicldingly hold the presserfootdown upon the fabric, the presser lifting lever 5 acting, at the willof'thc operator, on the extended portion 6 of the collar to elevate saidbar.

7 represents the presser-bar bracket secured by screw 8 to the bar 1,said bracket being cut. out at 9-to receive the latter bar and at itsopposite ends provided with bearings as 10 into which are looselymounted the clothpresser-carrying rods 11 and 12, each of the latterbeing provided with guide-collars, as 13, secured on said red by screws,as 1 L, each of said collars being provided with guidemembers, as 15,which track suitable guideslots, as 16, formed in the bracket 7';springs,

as 17, acting on the collar 13 to yieldingly hold the rockingpresser-feet 18 and 19 in their depressed positions.

20 and 21 denote presser-feet brackets carried by the rods 11 and 12respectively, and into said brackets are pivot pins, as 22, therespective Presser-feet '18 and 19, each of the latter bing providedpivotally connected by with needle openings, as 23, and needlethreadslots, as 24.

25 represents the guiding resser-foot bracket securedby screw 26 andpins, as 27, to the rear side of the bracket 7, and free end of thebracket 25 is'pivotally connected by pin 28 the guiding presser-foot529provided with the needle opening 30, 1V- shaped openingBO and guidingwalls 31 and 32, the receiving end of each of the clothpressers beingturned upward to better accommodate the feeding of the fabric to theaction of the needle.

The fabrics represented by 33 and 34:, Fig. 5, comprise portions of acorset as commonly assembled; 36 denoting the stay pocket tape and 37the rust-proof fabric with whiclr the inner sides of the staypockets, as38, are lined, the two portions 33 and 3% being provided with edge-foldswhich are superposed to receive the seam a, the

latter also acting to secure to said portions the fabrics 36 and 37 suchoperations being known in corset construction parlance as the joiningoperation, the seam, as 7), acting to secure the fabrics 3G and 37 tothe joined portions and 3st which form the pockets 38. thus the seams,as 7), are formed in four plies of fabric while the seam a coinprisessix plies, and further, in the manufacture of corsets it frequentlyoccurs that the body portions 33 and 34 are folded or joined by scamsarranged transverse to and crossing the present seams which furthercomplicatcs the problem of securely holding the fabrics down upon theusual cloth-plate and to overcome this difficulty is the purpose of thepresent invention.

To unite the fabrics as represented by Fig. 5, the free edge alOof thefold il tracks the vertical guide-wall 32 of the presser 529, thusinsuring that the several seams will be properly gaged, but should thejoining opto the To better adapt the present device to'aii,v

organized sewing machine for effecting a central chain-stitch and twoouter lock-stitch seams, as in my pending No. 817.737, filed Feb. iJ,1914, for improvements in sewing machines, the clothapplication, Serialpressers l8 and 19 are; provided with slots,

' as 24, to nizike convenient the passing of the needle-thread backunder the respective *prssers wvithoutrheing obliged to thread throughthe needle holes 23, but as the cen- Presser present above the fold orotherwise the free edgeO' tral presser l9 coacts with the chain-stitch'or seem a, it is preferable to omit slotting the clothpresser as it isdesirable that the a solid surface directly I springs 17.

Having thus set forth the nature of the invention, Whntl claim hereinis 1. In a clotl1-presscr mechanism for sewing machines, the combinationwith a main spring-depressed resser-bar carrying a rocking cloth-presserhaving ing comprising a continuous Wall, of independently mountedspring-depressed rocking cloth-pressers having independent depressingmeans and located one at one side and the other at the opposite side ofthe clothresser carried by said Ina-in prcsser bar, each of saidoutwardly arranged clothpressers being provided With a needle-openingand a thread-slot, the latter extending a needle openfrom theirreceiving ends into the needle opening.

In a cloth-presser mechanism for seW- ing machines, the combination witha main spring-depressed presscr-bar carrying it rocking cloth-Presserprovided with oppositely arranged guide-walls, of independently mountedspring-depressed cloth-pressers having independent depressing means andarranged one at one side and the other at the opposite side and normallybelow the cloth-presser carried by said main Presserbar.

3. In a cloth-presser mechanism for sewing machines, the combinationwith a main spring-depressed prcsser-bar carrying a rockingcloth-Presser having a ncedle-opening comprising a continuous Wall and aV- shaped opening at its receiving end terminating in guide-walls, ofspring-depressed rocking cloth-pressers' having independent pressingmeans and located one at one side and the other at the opposite side ofthe cloth'presser carried by said main presserher. i

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.
